Will the Java code display or download?

It displays as text in the browser, with formatting and indentation exactly as uploaded — so people can read it before copying or running anything.

Is it safe to host source code publicly?

The file is readable by anyone with the link, so it's fine for code you'd put in a public repository and wrong for anything containing keys, tokens or credentials.

Can I host a whole project?

Yes — upload the folder rather than a single file and it publishes as a set of files, or host a .zip of the project for people to download.

Host a Java file and share it as a link

Put a .java file at a public address that displays as readable source.

You can host:

Drop your Java file here

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site

Free to use. Your JAVA file is live at your-name.99helpers.site in about ten seconds.

What is a .java file?

Java is a compiled, statically typed language running on the JVM. A .java file is source that compiles to bytecode — so hosting one shares the code for reading, not something that runs on its own.

What people use JAVA files for

How to host a JAVA file

1
Drop your JAVA file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: example-class.99helpers.site
3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.

The same three steps work for any file — see how file hosting works on 99helpers.com.

What happens when someone opens the link

The source displays as text, formatting intact.

Why host a JAVA file instead of emailing it?

Course material and code examples need stable URLs that students and readers can return to. A link is simpler than a repository for a single class.

Worth knowing before you publish

Never include API keys, tokens or credentials — the file is public and can be indexed.
Note the language version and any dependencies in a comment, so whoever reads it knows what it needs.
For multiple files, upload the folder rather than each file separately.
